MM74C373 MM74C374 3-STATE Octal D-Type Latch 3-STATE Octal D-Type Flip-Flop October 1987 Revised January 1999 MM74C373 MM74C374 3-STATE Octal D-Type Latch 3-STATE Octal D-Type Flip-Flop General Description The MM74C373 and MM74C374 are integrated, complementary MOS (CMOS), 8-bit storage elements with 3STATE outputs. These outputs have been specially designed to drive high capacitive loads, such as one might find when driving a bus, and to have a fan out of 1 when driving standard TTL. When a high logic level is applied to the OUTPUT DISABLE input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements. The MM74C373 is an 8-bit latch. When LATCH ENABLE is high, the Q outputs will follow the D inputs. When LATCH ENABLE goes low, data at the D inputs, which meets the set-up and hold time requirements, will be retained at the outputs until LATCH ENABLE returns high again. The MM74C374 is ...
